is a plan view of the magnetic poles of the rotating magnet of the motor. This wire-wound coil has a 3-phase 8-pole structure, and forms a motor electromagnetic section that is stacked and fixed on the surface of the stator yoke 3, facing the magnetic pole surface of the flat rotor magnet 8. The coil for one phase is composed of one eight-pole flat coil, and the terminals of each adjacent coil pole are connected in a continuous manner in a single stroke, and the coils are wound in opposite directions. The conductor used is a self-bonding wire whose surface is coated with an adhesive that melts with heat or alcohol. A special winding machine is used to manufacture the coil. The wire is sequentially and continuously wound around eight triangular winding cores arranged in an annular manner while being heated or dipped in alcohol, and finally both the front and back sides are heated and pressed to form a flat shape. Two terminal leads 5 are taken out per one phase. These three flat coils are concentrically stacked and fixed with electrical angles of 2/3π shifted from each other in the circumferential direction. The terminals 5 of each coil are soldered and tangential to the pattern surface of the wiring board 9 fixed to the side surface.
A sensor 4 for detecting the rotational position of the rotor magnet 8 is fixed on the wiring board 9. The drive electronic circuit 74 is provided separately and is connected to the wiring board 9 of the motor.
The lead wire 93 and the connectors 82, 82' are connected to this. Furthermore, the electronic circuit 74 is connected to the connector 8
0,80' and a lead wire 94 to connect to the power source 73.

Each terminal of the sensor and FG is connected to an electronic circuit continuously using each connection lead pattern conductor as in the previous embodiment.
It is led to the component wiring sheet section 22. The bending points for lamination are A-A', B-B', C-C' and D.
-D', the surface portion 22 is placed at the bottom with the stator yoke 3 in between, as in the first embodiment. In this structure, since the number of coil poles is large, the effective conductor length can be longer than that of the coil of the first embodiment, and the motor efficiency can be increased. Other effects are similar to those of the first embodiment. In this structure as well, the number of coil sheet portions for each phase may be further increased continuously, and it is also possible to add a reinforcing plate or a heat sink to the sheet portion 22 of the circuit/component wiring portion.
